To all whom it may concern Be known that T, W. l rioro', a citizen of the United States, residing at Capron, in the county of l/Voods and State of ()klahoma, have invented a new and useful Motion-Picture-Film Winder, of which the following is a specification.

The present invention appertains to de vices for winding up motion picture films and the like, and aims to provide a novel and improved appliance of that nature for winding up a film with the forward end outermost, whereby rewinding is unnecessary, it being well known that films in being wound up in the ordinary manner, require a rewinding thereof to bring the forward end of the film outermost.

It is the object of the invention to provide a film. winding device embodying a novel assemblage of the component ele ments, whereby the film after passing through the projecting apparatus is wound up with its forward end outermost, in order that'the film need not be rewound for subsequent use, it merely being transferred from winding to unwinding position on the projecting apparatus or motion picture machine.

The invention has for a more specific ob.- ject, the combination with a reel having means at its periphery for the engagement of the forward end of the film, of means for applying the film to the reel whereby it is wound from the peripheral portion of the reel inward toward the hub, the convolutions or turns of the film being held together snugly during the winding thereof, and the reel being readily removed when tilled.

vVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the ac= companying drawings, wherein i ll igure 1 is an elevation of a motion picture machine illustrating the improved film winder applied thereto.

Fig. 2 is an enlarged side elevation of the device..

t8 the interior parts.

Fig. 5 is a view of the complete reel with the removable side plate attached thereto, portions being shown in section.

l 1g. 6 is a perspective view illustrating the means for attaching the forward. end of the film to the reel.

Figs. 7 and 8 are sectional views on the respective lines 7? and 8-8 of 2.

Fig. 9 is a sectional detail on the line 9-9 10 is an elevation of the film box with the cover removed and film holding wing or plate swung into position, the reel also being removed.

in Fig. 1, there is illustrated. the upper box 1 containing the reel. from which the film 2 is unwound to pass through the projecting apparatus to the lower film box 3 with which the present device is assembled, it being understood that the present construction can be altered, within the scope of what is hereinaf er claimed, in adapting the device to various makes of motion picture ma chines. The box 35 can be supported in any suitable manner according to the circumstances and in the proper position for receiving the film.

A stub shaft t is journaled for rotation through the back of the box or casing 3, and

is rotated as usual by means of a pulley wheel 4 attached thereto or in other suitable manner for winding up the film. A cover plate 5 is provided for the box 3 which is preferably of larger area than said box, and which is hinged, as at 5, to one edge of the box 3 to be swung open and closed any suitable means (not shown) being used for holding the plate 5 in closed position.

The reel which is placed removably within the box 3 embodies a hub 6 and a side plate or disk 7 permanently assembled with one end of the hub 6, said hub having a bore 8 of non-circular cross section to slip upon the shaft 4 within the box 3 when the cover plate 5 is swung open, whereby the reel will be rotated with said shaft, the reel being readily withdrawn when the plate 5 is swung open. The hub 6 is provided at its other end with a reduced boss 9 and a recess 10 surrounding said boss. An opposite side till llllti Lari! plate or disk 11 is provided for the .reel, the

4 same having a central hub section ed to be threaded onto within the recess 10. This plate 11 is only 12 adapt applied to the hub when the reel is removed with, the film wound thereon,-in which event the plate 11 can be applied tothe hub for shipping or handling the film. When the reel is within the box 3, the plate 11 is detached therefrom .and the plate 7 of the reel is adjacent to the back of the box.

A therefrom for the attachment of an attachprovided with a spiral slot 13 extending ing plate 14 curved slightly to conform to the curvature of, the slot 13. The plate 14 is provided at one'edge with parallel flanges '15 to overlap the'opposite sides of the plate 7, said flanges 15 being connected by a web to which moves longitudinally into the slot 13. Thus, when the web 16 is moved into theslot 13 with the flanges 15 overlapping the plate 7, the attaching plate 14 is firmly held in place.

The rollers 20' are mounted to move. inwardly as the of the film together snugly during the windi2ng thereof. One of said rollers, designated 08 pos ite to the roller 19 and is tapered. to properly guide the film 2- fromflthe slot'18into an annular path, as seen in Fig. ,4, around the rollers. As a means for mounting said rollers, the plate 5 is provided upon its outer ribs 21 having longitudinal bores 22in which plungers 23 are slidable radially. Said plungers have pintles 24 projecting through radial slots 24' in the plate the boss 9\and to fit 3. A. tapered is located at that end of the'slot 18 op-.

The plungers 23 have outstanding finger pieces 25 working in longitudinal slots 26 with which the ribs 21 are provided, and said plungers, have stems 27 projecting radially within the bores 22 from the center of the plate 5. Followers 28 are secured to the outer ends of the stems 27 and work within the bores 22, and coiled wire 29 are disposed Within the bores between the fdllowers 28 and partitions 30'withwhich the ribs 21 are provided within said-bores. Springs 29 are of sufiicient tension to move the followers 28 and plungers 23 radiallyoutward, to carry the rollers 20 with them,

said parts being yieldable inward.

The operation of the device is as follows: The reel is placed within the box- 3 after the cover plate 5 is swung open, the hub 6 being slipped plate or clip' 14 having been applied to the plate 7. The forward endof the film is then introduced through roller 19 and is moved around the roller 20 and engaged with the attaching plate'or clip 14. The cover'plate 5 is then closed. Now, when the machine is operated, the shaft 4'will be rotated, thereby rotating the reel, and the forward This will carry the film around the rollers 20, the film moving from the projecting apparatus past the roller 19, through the slot 18, and thence past the roller 20 and around the series of the film outwardly. The film is thus wound up within itself, instead of upon itself, as usual, so that the forward end will be outermost, and asthe film is wound up, the convolutionsbeing laid one within the other, this. will move the rollers 20 inwardly.

The rollers 20 will move lnwardly with the plungers or slides 23, pulling the followers 28 withthem to compress the springs 29.

This is accomplished bypressing the finger pieces 25 inwardly, lers 20 from the innermost convolution of can then be The inner or rear end of the film is then preferably engaged under the spring tongue 14', and the reel is then slipped off of the shaft 4 and canbe applied subsequently within the upper film box 1. to run the film through the projecting apparatus,w1thout the necessity of the film bethereby withdrawing the rol- V ing rewound as usual.

It is preferable to provide a plate or wing 31 pivoted, as at 32, to one of the upper corners of the box 3, and adapted to be swung downwardly across said box when the cover or door thereof is swung open, whereby to hold the film upon the reel,

Having thus described the invention, what is claimed as new is:-

1. A film winding device embodying a box, a cover therefor adapted to be opened, a removable reel within the box having means for carrying the forward end of a film therewith, yieldable means carried by the cover movable inwardly and around which the film is wound, said yieldable means being movable inwardly manually and means carried by the box movable to hold the film therein on the reel when the cover is opened. I
